ALSA: hda - add bounds checking for the codec command fields
A recent bug involves passing auto detected >0x7f NID to codec command,
creating an invalid codec addr field, and finally lead to cmd timeout
and fall back into single command mode. Jaroslav fixed that bug in
alc880_parse_auto_config().
It would be safer to further check the bounds of all cmd fields.
